In mobile phone case manufacturing, mold opening accuracy directly affects product quality and stability. Poor mold opening accuracy can lead to defects such as warping, uneven filling, or unstable part quality. For mobile phone case manufacturers, ensuring the highest level of mold opening accuracy is crucial to reducing waste and maintaining product quality. Therefore, a… Continue reading Fixing Poor Phone Case Mold Opening Accuracy: Mobile Cover Making Machine’s Precision Tuning

For medium-sized plastic product manufacturers, the choice between a 170 ton and a 260 ton machine typically depends on product size and material requirements, which directly impact part quality, production efficiency, and procurement budget. Therefore, we have compared the production capacity, application range, mold requirements, and material compatibility of the 170 ton and 260 ton… Continue reading 170 ton vs 260 ton injection molding machine: Product Capacity & Application Scope

Choosing the right injection molding machine manufacturer is one of the most important decisions for plastic product buyers. The injection molding machine purchased determines part quality, uptime, energy costs, labor requirements, and ultimately impacts time-to-market. Therefore, buyers need clear and practical criteria to evaluate suppliers. You can consider them based on technology, quality control, service,… Continue reading How to Choose a Reliable Injection Molding Machine Manufacturer: 6 Key Criteria

For today’s manufacturers, balancing productivity, quality, and sustainability is crucial. Traditional hydraulic injection molding machines, while reliable, consume a significant amount of energy; all-electric injection molding machines solve the energy problem, but have high initial costs and limited flexibility in heavy-duty applications. A hybrid injection molding machine combines the best of both worlds, integrating the… Continue reading Guide to Hybrid Injection Molding Machine: Servo-Hydraulic Synergy for 40% Energy Savings

Poor plasticization in the injection molding process can lead to bubbles, uneven surfaces, or brittle edges on parts, making them unsuitable for quality inspection. This not only wastes raw materials but also consumes time and increases labor costs. The main problem lies in poor management during the pre-plasticization stage; unstable pressure or temperature can cause… Continue reading How to Solve Poor Plasticization in the Injection Molding Process？

Inefficient injection molding operations are often caused by delays between steps, resulting in lower overall efficiency. For example, a slow-responding dryer causes the molding machine to be idle; drifting mold temperature controllers result in scrap. As a result, operators waste two hours a day switching between five different control interfaces. This lack of equipment coordination… Continue reading How to solve the problem of low production efficiency: Topstar’s molding machine to improve overall efficiency by 15%

A car interior parts manufacturer was struggling with problems with cold-runner injection molds. Their products suffered from defects such as shrinkage marks, short shots, and uneven wall thickness, all stemming from “low-temperature dead zones” in the runner system, where the temperature is 15-20 degrees Fahrenheit below the set value. Their traditional on/off mold temperature controllers… Continue reading Guide to PID control Mold temperature controller: Fix Low-Temperature Dead Zones in Cold Runner Injection Molding

A consumer electronics miniature connector manufacturer found that their existing hydraulic injection molding machine couldn’t generate enough stable ejection force to eject high-precision USB-C connectors smoothly. 12% of their monthly production was scrap—parts stuck in the mold, pins bent, shells cracked—due to either a malfunctioning ejection mechanism or excessive ejection force. Clearly, this was due… Continue reading Servo-driven injection molding machine for easier connector demolding: 20% increase in ejector thrust

With the widespread adoption of digitalisation across various manufacturing sectors, many injection moulding plants are striving to maintain competitiveness, driving an increasing demand for intelligent injection moulding machines. By integrating intelligent technologies such as the Internet of Things (IoT), artificial intelligence (AI), and injection moulding machine learning, these machines not only improve production efficiency but… Continue reading The Importance of Intelligent Digitalization in the Future Development of Injection Moulding Machines

Low cavity fill rate is a significant challenge in high-speed injection molding. For products such as thin-walled containers, caps, or blister packaging, even a cycle time reduced to 3-5 seconds can lead to a 5% decrease in output and a 20% increase in scrap costs. The primary reason for this is the mismatch between injection… Continue reading Solving the problem of low cavity filling rate in high-speed packaging injection molding

The screw in an injection mold machine primarily functions to melt, mix, and precisely inject plastic. Choosing the wrong screw can lead to scrap, delays, and material waste. Selecting the right screw ensures consistent quality and lower costs. The choice between a single-screw and a twin-screw injection mold boils down to one question: what material… Continue reading Injection Mold Machine Screw Selection Guide: Single Screw vs. Twin Screw Selection

Precision plastic parts, such as medical components, automotive sensors, or electronic housings, require extremely high consistency. Even a deviation of 0.01 mm can render a part unusable. Hydraulic injection molding machines, due to their fluid-driven motion, struggle with pressure fluctuations, leading to uneven clamping and slow response times, which in turn cause injection instability. All-electric… Continue reading Guide to All-Electric Injection Molding Machine for Precision Plastic Parts: 90T-200T TEII Series
